Abstract
A 3D conversion lens and a control method thereof are disclosed. The 3D conversion lens has a first substrate and a second substrate, the first substrate and the second substrate forming a box; electronic ink, the electronic ink filling in the box cavity of the box, and the electronic ink has opaque charged particles, the opaque charged particles have opaque pigment; an electrode formed on the first substrate; and an electrode formed on at least one side wall of the box cavity. With the conventional liquid crystal layer replaced by electronic ink, 3D display effect of the glasses is realized by controlling positive and negative polarity of the transparent electrodes on the substrate and the side wall of the box cavity. In this way, it is unnecessary to control and realize deflection of the liquid crystals, which simplifies the circuit structure and the preparation process of the 3D glasses.
